Check engine light on a 99 cougar

Is there a fuse i can pull to turn this off? I have been told the onboard computer is bad and there is no problem. Other than the annoying light.

Unfortunately that light is intergrated to the ecm and can not be turned off unless you clear the code or replace the defective computer. most guys i talk to just use a piece of electrical tape to cover the light. but that is up to you. hope this helps

The engine light on my 96 merc cougar XR7 is on. Car shakes bad when i accelerate and engine light begins to blink. I'm embaressed to say my engine light has been on for sometime but was told it c


The check engine light needs to be addressed. Yes it could be a sensor but you need to know.
The light blinking means the problem is serious, such as a dead miss on one or more cylinders. The light being on means something is happening with the engine performance that could damage the catalytic converter.
Get the computer scanned - most auto parts stores will do it for free in hopes of selling you some parts. Once you have the codes research them online or here.

Rotten egg smell??? Thats smell could be either from a bad 02 senser or a totally clogged catalytic converter...not terribly expensive to replace. As far as the engine shaking, and it not going quick out of the stop light, I'd pull my tranny dipstick and smell the fluid and check for a buring smell and or the color. You want it to be a light red color. You may have an internal transmission issue. You said you got "fluild" out of your tailpipe, was it just water, or was did it have a scent to it. You really should have the car checked out, with those symptoms that you listed you could do more damage by still driving it that way.

check the fuel pump relay and try to hear if you can hear anything coming from the fuel pump and also check the fuse for the sending unit.

Tail lights dont have power 99 cougar


did you check the relay? it would be in something that looks like another fusebox under the hood, in the engine compartment. if its not a bulb, fuse or relay, then it is a wiring problem.
